Abstract
The present disclosure generally pertains to systems and methods for swapping span power modules that are used for supplying power to network interface units (NIUs). A span power module in accordance with one exemplary embodiment of the present disclosure has logic capable of communicating with logic of another span power module. When one module is to be swapped for the other module, the module being swapped-in is configured to automatically disable the other module shortly after it has powered up and is supplying electrical power across a span line. The amount of time that both modules supply power to the span line is sufficiently small such that damage to electrical communication equipment receiving power from the span line is prevented.
